IMl?ROVBMBNT IN- DRAUGHT-EQUALIZBR FOR DOUBLE-TREB.

Be it known that I, ROBERT F.JDSON, of Kalamazoo, in the county ofKalamazoo, a ud State of Michigan, have invented a'new and usefulDraught-Equalizing Double Wl iiflleTree; and I doherehy declare that thefollowing is a full, clear, and exact description thereot, referencelieing had to the aceompanying drawings, making part of thisspecification. i V V Figure 1 -isa perspeotiveview. Figure 2,longitudinal view of curved levers, with whifile-tre attached; leversunited by the bolt shown in fig. 6

Figure, 3, longitudinal view of draught-iron, or improved clcvis. i

: Figure 4, side view of improved clevis. Y

Figure 5, king-blt. A

Figure 6, holt with eye at the top for conheoting curved levcrs. Y

Thenature of my intoutiou consists substimtially iu attaching to thepole.ofa buggy, wagon, sleigh, reaper, or mewer, by meims of a kingboltat the forward end, and a'staple at the rear end, a clevis ordraught-iron, having ahook on each side, and near the forward end, alsoa hook on each side end near therear end, which passos under the staple.To these hooks are attached two stay-chains, which stay-chains areattached by hooks 'to the ends ot' the short arms of two curved or bentlevers, crossing each other, and united at the point of croSsing by abolt with an eye at the top. At the rear of\the hent levrs is astaplc,attached to the clevis,

' bent at right angles, and passing forward through the eye of the boltuuitixig the bout Icvers, for the p'urpose of stetdying the same, alsoto prevent-the tvhifile-trees from scraping the wheels. To the long armsof the bout -levers are attached ordinar'y small whifile-trees'h Thestay-chains may be used for all heavy-draught purposes.

For light-draught buggies or sleighs, wood or leather l raees may heused iu the place of the stay-chains, being united byjoints, buttons, orhooks, with the ends-of the short aims of the .bent levers, and theforward and rear ends of,the iron clevis.

The invehtio,n has for its object the 'preventing of a quicker orstronger horse from obtining an advantagcover a slower or wea-ker one;also to cause the stronger horse to aid the weaker, in proportion as hisstrength is greater, and to prevent the whifile-tree from scraping thewagon-wheels;

To enable others skilled inthe art to make anduse my invention, I willdescribe its construction and operation. Y

The bcnt levers, fig.'2, with whifile-trees attached tothe end of eachlong arm, and hooks-to the end of each short arm, are united, as theycross each other, by the holt, fig. 6, headed o'n the under side of thelovers,

and having an eye at the top. The lovers are attached to the ironclevis, fig. 3, by means of a staple, near the rear end of the clevis,fig. 4, bent forward at right angles, and passing through the eye of thebolt uniting the lovers. This staple answers the purpose of steadyng thelevers in their places, and also prevents their slipping back so as toscrape the wagon-wheels. To the liooks on the ends of the short arms ofthe hent levers, aro attached stay-chains, as seen in fig. 1, by meansof passing a link of each chain over each hook, which staychains areattached to the iron clevis by hooks on each side, and near the forwardand rear ends of the same, (fig. 1.) The stuy ehains are attached to theshort arms of the bent levers,so that the portion of each chain, forwardof the lovers is shorter than that back of the seme. The stay-chains mayhe shortend or lengthened at pleasure. The iron clev is is attached tothe pole by means of the king-holt, fig. 5, near the*forward end, and astaple, under which the rear end passos, fig. l.

With the stay-Chains hooked so that the boltuuiting the bentlcverscannot be crowded forward of the line of the hoohs, at their short ends,the animal,pulling on the whifile-tree, et one end of the lovers, at thesame time, by means of saidbolt, crowds forward the opposit lever, thusrendering it impossible for him to secure an advantage over his mate.For the sanie reason, the instant he pulls more than the oppositeanimal, he aids him in that proportion. When the animals-slacken thedraught, the staple, passing through the eye of the bolt uniting thelovers, preventa the whflle-tree sraping the wagon wheels.

Having described my invention, what I claim as new, and desire to securehy Letters Patent, is-- The combination of the stay-chains, or wood orleather bruces, the curved levers, crossing each other, and

united by a bolt forming a. joint, the iron c1evis, the staple in theclevis, the king-bolt, the st'x ple attaching rear end of clevis to thewagon-pole, the small whfiie-tree, wjth the wagon pole, for the purposesset f0rth and described.
